Question

b. Equilibrium is necessary in the various
bio-geo-chemical cycles.​

Answer 1

Answer:

The most important biogeochemical cycles are the carbon cycle, nitrogen cycle, oxygencycle, phosphorus cycle, and the water cycle. The biogeochemical cycles always have a state of equilibrium. The state of equilibrium occurs when there is a balance in thecycling of the elements between compartments.

Answer 2

Explanation:

i. Human activities on the large scale such as clearing forest or cutting of trees on large scale (deforestation), burning of fossil fuels, more use of chemical fertilizers, and pesticides.

ii. These activities disturb the biogeochemical processes, directly or indirectly.

iii. Some steps should be taken to maintain the biogeochemical equilibrium in the ecosystem such as:

1. Plant more and more trees to maintain oxygen and carbon dioxide balance in nature.

2. Least use of chlorofluorocarbons.

3. Reduce vehicular pollution.
